 ### Direct CSM Implementation
 
-EchoForge includes a direct CSM implementation that bypasses adapter layers and directly uses the CSM model. This approach offers several advantages:
+EchoForge now uses the Direct CSM implementation by default for faster voice generation, especially on CUDA-enabled devices.
 
-- **Improved Performance**: Direct access to the model reduces overhead
-- **Better Audio Quality**: Fewer transformations lead to clearer voice output
-- **Simplified Architecture**: Reduces complexity in the voice generation pipeline
-- **Fallback Mechanisms**: Automatic fallback to CPU if CUDA fails
+#### Features
+- Up to 25x faster generation on GPU compared to CPU
+- Maintains the same high-quality voice output
+- Automatically falls back to CPU if CUDA is unavailable
 
-For more details, see the [Direct CSM documentation](docs/DIRECT_CSM.md).
+#### Usage
+To start the server with Direct CSM enabled:
+```
+python run.py --direct-csm
+```
+
+When using the API, specify `device=cuda` for faster generation:
+```
+curl -X POST http://localhost:8779/api/generate \
+  -H "Content-Type: application/json" \
+  -d '{"text": "Your text here", "voice": "male", "temperature": 0.7, "device": "cuda"}'
+```
+
+#### Performance
+- CUDA generation: ~3-6 seconds
+- CPU generation: ~150 seconds

+**Parameters**:
+- `text` (string): The text to be converted to speech
+- `voice` (string): Voice type to use ("male", "female", or "child")
+- `temperature` (float, optional): Sampling temperature for generation (default: 0.7)
+- `top_k` (integer, optional): Top-k sampling parameter (default: 80)
+- `device` (string, optional): Device to use for generation ("cuda" or "cpu", default: "cpu")

+**Example**:
+```bash
+curl -X POST http://localhost:8000/api/generate \
+  -H "Content-Type: application/json" \
+  -d '{
+    "text": "Hello, this is a test of the voice generation system.",
+    "voice": "male",
+    "temperature": 0.7,
